I try to avoid salt as much as I could .. But that's just me.. I think your son rejects porridge coz he's used to tasty porridge? How old is your son now? Maybe you can try introducing other things? Such as kway teow soup? You can cook the kway teow in chix stock with sliced fish and some veggies.
Orange vegetables contain beta-carotene. It can cause skin to turn yellow/orange. A bit is fine. dont't overdoes.
He is around 6mths 1-2 week now...
i started when he was around 5 mths 3 weeks, only let him taste taste nv feed everyday... it was around 6mths i feed him everday... he learn to eat bit by bit abt 1 week+ when he can eat around 2 tablespoon , then he suddenly totally he reject... i was still using the same thing to cook, except removing the carrot...
so i dun know whether its due to no carrot or??? but i dun think its the carrot... can't pin point where is the problem.... after he reject he wanna drink milk instead... he can drink his full bottle or even more milk than usual... so confirm he is hungry, but why he dun wan porridge??
even cereal also dun wan... so now stop temp, feeding milk only now... let him rest and try again..
